Hello T.M.,
I've just been reading this thread, and whilst I can't add any more advice onto what people have already told you, I just thought I'd say Hi and let you know that you aren't the only one in your situation - I live with my parents and I am older than you! I also earn roughly the same as you, and I also had the same level of debt, initially I went on a Debt Management Plan before I went on an IVA, in a way I wish I'd begun the IVA to start with, but it did "train" me for the monthly budgeting, which seems to be the hardest thing for a lot of people.
I'm glad you were able to tell your parents, mine are brilliant but money is a sticky subject due to issues with other family members, my mum knows I owe something and I am paying it back, but she refers to it as my "problem" which is what the IPs etc. advise against!
I have a newer car than you (bought with cash which I made from a company share issue), but like you say I haven't got a lot of stuff to show for it either - my biggest thing was getting a consolidation loan over 84 months from Nat West for £16,000, which with the APR came to almost £25k itself. I did get it down a bit, but I still used cards in the meantime.
Anyhow, like I said, I can't really offer much more than what folks have said, but I just wanted you to know that you weren't the only one! All the best with whatever you decide to do xxxx
Final payment 1st April 2016.
Completion Certificate received 19th May 2016.
